Definitions

  • the invention relates to a clamping system for fixing workpieces.
  • machining of metallic workpieces is often very complex and can include a variety of machining and cutting operations on different machine tools to produce the finished workpiece.
  • the workpieces are clamped between jaws on a support plate, or they are glued into prepared openings, but then long waiting times are required until the actual processing can be started.
  • the object of the present invention is in particular to propose a clamping system with the shortest possible set-up times, which can be operated with simple steps and is also suitable for different workpiece sizes.
  • the invention is achieved in that it has a stop element, at least two arms and at least one clamping bracket, wherein in the stop element, in the arms and in the clamping device means for positive, screw-free connection of the stop element with the Jibs on the one hand and for connecting the boom with the clamping bracket on the other hand are provided to form a stable frame.
  • the clamping system is characterized in particular by the fact that a clamping frame of different parts without screws is frictionally plugged together and on the one hand more than a workpiece and on the other hand workpieces of different sizes are clamped.
  • the clamping system in particular the set-up times are reduced to nearly 60% compared to the prior art.
  • the handling is very simple. Therefore, the work preparation can be done in an optimal way.
  • the clamping system is characterized by a small number of individual elements.
  • the clamping system is equipped with a reference element for connection to a reference clamping system or zero point clamping system, wherein the reference element is formed for example as a pallet, as a pin or the like.
  • the connecting means of the individual parts to be joined together are preferably conical connectors of various forms and sizes.
  • the clamping system in particular the clamping frame is formed form-fit, non-positive and screw-free. Only the actual workpiece is clamped by means of screws or set screws to the stop element. To give the tenter additional dimensional stability and wear resistance, all components can be hardened. Another advantage of the clamping system is that the machining can be vibration-free.
  • the clamping system is characterized by high flexibility in the configuration of the workpiece holders.
  • a clamping system is shown with a clamped workpiece 7, the clamping system consists essentially of a frame 9, which is formed from a stop element 1, two arms 2 and a clamping bracket 3.
  • the stop element 1, the two arms 2 and the clamping bracket 3 have connecting means 4, which are designed as plug-in connections.
  • the connecting means 4 are conical, which ensures a stable frame.
  • threaded holes 6 are provided for screws 8 for clamping the workpiece 7.
  • the versatility of the clamping system shows Fig. 2 ,
  • two workpieces 7 of different sizes are clamped by forming two frames 9.
  • the two frames 9 are formed by the stop element 1, by three arms 2 and by two clamping bracket 3.
  • the flexibility is achieved by the multiplicity of connecting elements 4 in the stop element 1, the arms 2 and the clamping straps 3.
  • the two workpieces 7 are held firmly by the guided in the threaded holes 6 of the clamping bracket 3 screws 8.
  • the clamping system of Fig. 2 is in perspective Fig. 3 shown.
  • a reference element 5 is attached to the underside of the stop element 1. This reference element 5 serves to use the clamping system in conjunction with a reference clamping system or a zero point clamping system.
